What will be the output of the code snippet when the user enters 23 and 45?

The output of the code snippet given that the user enters 23 and 45 will be 2345. This occurs because the code likely concatenates the two input values as strings rather than performing a mathematical addition.

When the user enters the values 23 and 45, they are typically read in as string data types in many programming languages by default. When two strings are concatenated, they are combined end-to-end. Thus, "23" concatenated with "45" results in "2345".

It's important to recognize that if the intention was to perform mathematical addition, the input values would need to be converted from strings to integers. If converted, the output would represent the sum of the two numbers, which would be 68. However, without that conversion, concatenation occurs, leading to the result of 2345.
